TUBE SEWING AND TURNING' MACHINE.

Patented Dec. 13, 1910.

Application led April 19, 1910. Serial No.^556,377.

To all whom it may concern:

Be it known that I, JOSEPH Pennant, a citizen ot' the United States,residing at Versailles, in the county of Morgan and State ot Missouri,have invcuted'new and useful Improvements in Tube Sewing and TurningMachines, ot' which the following is a specification.

This invention relates to new and useful improvements in apparatus forsewing and turning tubular bagging at'ter the meeting edges are broughttogether and stitched and aiiords a simple and eflicient automaticv.means whereby the tubing, the seam of which is stitched by a machine,may be drawn through the ring or ellipse and held by means of a suitablestretcher mechanism, after which it is wound upon a reel.

The invention comprises Various details of construction and combinationsand arrangements of parts which will be hereinafter fully `described andthen specifically defined in the appended claims.

My invention is illustrated in the accom-4 panyingidrawings, in whichFigure l is a perspective View of the ap# paratns embodying the.features of my invention. Fig. 2 is an enlarged detail perspective viewof the ring or disk through which the tubular fabric after having beenstitched is drawn and the stretcher arm. Fig. 3 is a top plan view ofone form of stretcher arm. Fig. 1l is a View iu elevation showing amodified form of the stretcher bar in which spiral springs are utilizedin connection with the telescoping sleeve carrying a wheel for engagingthe seam after -having been sewed. Fig. 5 is a detail perspective viewot an idler mechanism -to cause the belt to draw taut and insure thetubing beingwound properly upon the reel, and Fig. 6 is a sectional viewon line 6--6 of Fig. 5.

Reference now being had to the details of the drawings by letter, Adesignates a table to the edge of which is tastened, as at B', a rigidrod B which preferably is curved over the top of the table as shown, andthence extends forward to a location, preferably slightly beyond the endof the table and terminates in a ring or disk C, which ring may beflattened or oi' any desired shape and preferably rounded upon thebearing edges a ainst which the tubing draws 1n a manner nich will behereinafterfully described.

over the top of the table to a suitable locai tion. Fastened to the barE is a block F and to which a resilient stretcher armG is fixed, saidarm being spaced apart :trom the bar E a short distance, preferably oneinch for ordinary work, and at the end ot said arm G is journaled awheel Il, the circumterence of which is grooved and adapted to receivethe seam of the tubing after the latter has been turned. A. wheel K,preferably with a convexed edge, is journaled in the free curved end ofthe bar or rod ll and provided for the purpose of causing the tubing tobe drawn taut as it is wound upon the reel, which will be presentlydescribed.

An adjusting member, designated by letter I, is )rovidcd with twoapertures, one designate( by letter L :for the reception of the bar Eand the other the resilient arm G, as shown clearly in Fig. 2 andall'ordiug means whereby, as said member is moved toward the free end ofthe rod E, said stretcher arm may be drawn toward the bar or rod E toregulate the tension ot' the wheel carried thereby against the seam ot'the tubing. A slight depression, designated by let ter J, preferably ofa depth suilicient to receive the scam ol the tubing, is lormedin thering or ellipse for the purpose oi receiving the seam and guiding thetubing therein as the latter is being turned.

sev

lVound upon a reel L which is vertically l disposed and journaled at itslower end upon the table and its upper end in a bracket arm L is thecloth or fabric N from which the tubing is to be formed. Said reel maybe positioned at any suitable location, preterably as illustrated, thetwo edges ot' the cloth .being drawn togetlier, one edge passing hand orany suitable nuehanisni.

bracket plat-es M upon-the table are the rollers O, between which thefolded tubing` passes, being frictionally drawn or fed .tor-

ward by saidrollers. Said folded tubing passes between the rollers U,thence extends to and winds about the reel R journaled in suitablebearings in the [standards l. A pulley R is tixod to the spindle ot thereel and abelt R2 passes about the pulleyv R and also one part of thedouble pulley R3 journaled upon the standard l and power is applied tothe pulley It through the inediuin of the belt O3 which turns about apulley Rl upon the sewin` machine, asshown clearly in Fig. l of thedrawings'7 power being applied to the pulley upon the. sewingmachine-"through the medium of the vertically disposed beltinginterposed between therollersl O and the reel it is an idler Q, thespindle ends of which are `iournaled in the.spring-pressed blocks Q2movable wi thin the standards Q3. rising from the table. A pulley Q" isfixed to and moved with the spring-pressed block Q2 and bears againstthe belt- 03.

.ln Fig. si. oiC the drawings, l have shown a slight modification ot theinvention in which a spiral spring 5 ls attached to the Astretcher baror rod 'l and S designates a sleeve telescoping within the lateralexten-` sion ot the stretcher bar and having jourvnaled therein thegrooved wheel t3, thus at 'tording a slightly modified means for holdingthe wheel securely against the seam. Said spiral spring should be ot'such a strength as will Vtirinly stretch thefabrie to hold the same tautand 'without its being torn. lVhere a less tension is required upondelicate fabric, lighter springs may beeinployed for regulating thepressure bearing against the saine.

The operation of my invention will be readily understood and is asfollows:-'l`he cloth or other vit'abric. to be converted into tubing isplaced upon the reel L, the two loi'igitudinal edges o they clothbrought together, one edge passing over and the other edge passing`under the rod B which terminates in a ringv or disk C, then under thearm olf the sewing machine and stitched together, the two edges beingheld and guided by the Atte1 i 'portion of the tubing' has beenstitched, it is drawn over the ring or ellipse C, through the latter andover the ends of the stretcher bar and gspring;` and ted between therollers O which serve to :feed the cloth for stitching and also forreeling' up after the. tubing has been stitched. the rollers draw the`tub ing:v rearward.' the edges of the cloth are brought underneath `thesewing machine and stitched; and`v as` the tubing' passes over the'marginal edge ofthe ring, it is turned outside in, the seam dr 'wingthrough the offset formed inthe ringffaiithby the provision of l thestretcher arms, the necessary tension may bel applied to the 'seam 'andalso at a' location (.l-iainetrically opposite to hold the tubing taut,the latter being guided by a grooved' pulley in the resilient stretcherarin. ln the evenil olf there being slack in the tubing behind therollers the idler Q will serve to hold the same taut and to cause thetubing to wind smoothly upon the reel R.

It' desired to sew `tnbings of different diameters, bars having rings ofthe desired diameter may be employed and also lreels and rollers ofcorresponding size.

Frein the foregoing, itwill be noted that, by the provision of anapparatus as shown and described, a simple and eilicient n'ieans isa'ti'orded whereby' tubing may be formed and automatically reversedandwound upon suitable reels or, it desired, may be fed to printingmachines or presses for further op eration, after which. the tubing' maybe eut into suitable .length and bottoms sewed.
